“…Unfortunately, in the real world, the etchant composition changes continuously. As an n-valent metal is dissolved into solution, etchant is consumed and the by-products of ferrous chloride (FeCl3) and metal chlorides are generated [5].…”

The conventional machining deals with the removal of metal by direct contact between the tool and the work piece, which results into the formation of chips, debris etc. So, there is scope for unconventional machining process like PCM. This paper focuses on study of Depth of etching in photochemical machining by varying temperature and time of etching. The objective is to study the effect of these parameters and find relation between them. This process is the bridge between 2D and 3D manufacturing processes. Initially the photo-tools are prepared; Brass material was taken for experimentation. The control parameters were temperature, concentration and time. The concentration of etchant (FeCl 3) was 781 grams per liter. The temperature and time are varying parameters for etching. The readings are taken by Digital Micro-meter. A pattern may be transferred onto a photoresist film by exposing the photoresist to light through a mask of the pattern called photo-tool and obtain pattern on metal.

“…Chen et al [ 7 ] investigated the impact of hydrofluoric acid (HF) concentration in the etching solution on etching efficacy and found that the morphology of the channel could be altered by manipulating the proportion of HF present in the etching solution. Saraf et al [ 8 ] identified that the surface roughness after etching was greatly influenced by the etching duration and etching solution composition, rather than temperature, which had a negligible impact. Agrawal et al [ 9 ] used FeCl 3 to etch 304 stainless steel and found that the surface roughness and the nonuniformity of the flow path edge increased with the increase of etching time.…”

T The chemical etching method has the advantages of high precision and low cost for the preparation of steel surface microchannel, but the composition of the etching solution and the etching process have a great influence on the precision of the microstructure. In this paper, the influence of etching solution composition and the etching time on the etching precision of stainless steel using a mixture of HCl and H2O2 as an etching solution was studied. The reactions and passivation processes that occurred during the etching process were analyzed. The etching mechanism was revealed. The sample prepared with HCl:H2O2=1:2 can obtain better etching precision and high dimensional stability. The amount of lateral erosion and the depth of etching increased with the increase of etching time, resulting in a decrease in the etching factor and precision. Pitting and intergranular corrosion mainly occurred during the etching process, and the loss of metal chloride formed in the process would form holes, which would become rapid diffusion channels for corrosive Cl and O elements, and promote the etching process. The etching reaction formed a passivation film on the surface of the substrate, which reduced the rate of the etching reaction.This article is protected by copyright. All rights reserved.

“…For this study we have kept following parameters as constant; developing time as 120 seconds, concentration as 400 grams per liter and etching time as 300 seconds PCM combines chemical etching with micro-photography and photosensitive etchant. Cakir [4]and Saraf et al [5]studied the effect of concentration, temperature, additives and etching time on responses like etch rate and surface finish for copper etching. Cakir [4] also studied the simultaneous regeneration of waste etchant.Atul R. Saraf and MudigondaSadaiahet al [6] studied Magnetic field-assisted photochemical machining (MFAPCM) of SS316L and found that the etch rate is higher at higher temperature due to the higher rate of collusion between the atoms.N.D.Misalet al [6]…”

The conventional machining deals with the removal of metal by direct contact between the tool and the work piece, which results into the formation of chips, debris, burr, etc. So, there is a huge scope for unconventional machining process. This paper focuses on study of Depth of etching in photochemical machining by using colored photo tool. The objective is to study the effect of different colored photo tools and achieve the stepped structure at micro level. This process is the bridge between 2D and 3D manufacturing processes. Initially the colored photo-tools are created; copper material was selected for experimentation. The control parameters selected were temperature, concentration and time. The concentration of etchant is 400 grams per liter. The temperature of the etchant is 50 degree Celsius and the time for etching is 300 seconds. The readings are taken by Digital Micro-meter.
